Microsoft's Lumia Selfie app for Windows Phone scored an update today in the Windows Phone Store. The small update is actually for Windows 10 Mobile preview users. The app now supports Bluetooth selfie sticks with Windows 10 Mobile.
That's the only change that's mentioned in the update notes for Lumia Selfie, which has been designed to help owners of Lumia smartphones take the best selfie image they can with special auto enhancements, filters and more. If you have downloaded the new Windows 10 Mobile preview build 10512 on your Lumia device, you should be able to use the app with a Bluetooth selfie stick for the first time.
